sheets = airport_df.sheetnames

sheet_first = sheets[0]

ws2 = airport_df["Sheet2"]#读取excel中第二张表
movement=[]

for i in range(1,ws2.max_column+1):

        cellr=ws2.cell(j,i)
        movement.append(cellr.value)

ln_movement=[]    
for j in range(len(movement)):
    ln_movement.append(math.log(movement[j]))###计算对数值
    

mt=DataFrame(ln_movement,index=range(1,631),columns=["movement"])  建立
mt.describe()###描述统计

运行结果如下：
